Andreas,

I think there are a lot of people on this list that would argue with 
that statement.  As was mentioned earlier, AT&T, Verizon, and several 
others including Verisign have very ample networks capable of handling 
attacks just as large as Prolexic, if not bigger.

One thing to note about Prolexic, where it stands out from some of the 
others is that it is a completely off-net solution.  Many of the other 
offerings from folks like Verizon require you to have WAN circuits 
connected to their network in order to avail of such a service (in other 
words, they will only scrub that which would normally traverse their 
network on it's way towards your WAN interface).

Others like Verisign have (smartly) adopted a similar model to that of 
Prolexic.  They understand that requiring a physical connection into a 
provider's cloud is a monolithic approach (and certainly runs counter to 
today's mantra of offering up cloud-based services).
